While there are many approaches for automatically proving termination of term rewrite systems,
up to now there exist only few techniques to disprove their termination automatically. Almost all
of these techniques try to find loops, where the existence of a loop implies non-termination of the
rewrite system. However, most programming languages use specific evaluation strategies, whereas
loop detection techniques usually do not take strategies into account. So even if a rewrite system has
a loop, it may still be terminating under certain strategies.
